Empirical estimation of statistics

In this example, we want to empirically estimate statistics associated with the range of the Mission discipline of the Sobieski’s SSBJ problem.

For simplification, we use uniform distributions for the discipline inputs based on the bounds of the design parameters.

from __future__ import annotations

from gemseo.api import configure_logger
from gemseo.api import create_discipline
from gemseo.api import create_scenario
from gemseo.problems.sobieski.core.problem import SobieskiProblem
from gemseo.uncertainty.api import create_statistics

configure_logger()
<RootLogger root (INFO)>

Create the dataset

First of all, we create the dataset. For that, we instantiate the discipline SobieskiMission of the Sobieski’s SSBJ problem which is known to GEMSEO.

discipline = create_discipline("SobieskiMission")

Then, we load the design space of the Sobieski’s SSBJ problem by means of the property SobieskiProblem.design_space() and DesignSpace.filter() the inputs of the discipline SobieskiMission.

parameter_space = SobieskiProblem().design_space
parameter_space.filter(discipline.get_input_data_names())
<gemseo.algos.design_space.DesignSpace object at 0x7f872028a2e0>

Then, we sample the discipline over this design space by means of a DOEScenario executed with a Monte Carlo algorithm and 100 samples.

scenario = create_scenario(
    [discipline], "DisciplinaryOpt", "y_4", parameter_space, scenario_type="DOE"
)
scenario.execute({"algo": "OT_MONTE_CARLO", "n_samples": 100})

Create an EmpiricalStatistics object for all variables

In this second stage, we create an EmpiricalStatistics from the database encapsulated in a Dataset:

dataset = scenario.export_to_dataset(opt_naming=False)
analysis = create_statistics(dataset, name="SobieskiMission")

print(analysis)
    INFO - 10:44:03: Create SobieskiMission, a EmpiricalStatistics library.
SobieskiMission
   n_samples: 86
   n_variables: 5
   variables: x_shared, y_14, y_24, y_34, y_4

and easily obtain statistics, such as the minimum values of the different variables over the dataset:

print(analysis.compute_minimum())
{'x_shared': array([1.13352258e-02, 3.01398316e+04, 1.40041295e+00, 2.55929483e+00,

Create an EmpiricalStatistics object for the range

We can only reduce the statistical analysis to the range variable:

analysis = create_statistics(
    dataset, variables_names=["y_4"], name="SobieskiMission.range"
)
print(analysis)
    INFO - 10:44:03: Create SobieskiMission.range, a EmpiricalStatistics library.
SobieskiMission.range
   n_samples: 86
   n_variables: 5
   variables: y_4

Get minimum

Here is the minimum value:

print(analysis.compute_minimum())
{'y_4': array([-1532.4108456])}

Get maximum

Here is the maximum value:

print(analysis.compute_maximum())
{'y_4': array([62030.01439676])}

Get range

Here is the (different between minimum and maximum values):

print(analysis.compute_range())
{'y_4': array([63562.42524236])}

Get mean

Here is the mean value:

print(analysis.compute_mean())
